The leaders of the free world descend on Scotland for an international conference, and every cop in the country is needed for frontline duty...except one. John Rebuss reputation precedes him, and his bosses dont want him anywhere near Presidents Bush and Putin, which explains why hes manning an abandoned police station when a call comes in. During a preconference dinner at Edinburgh Castle, a delegate has fallen to his death. Accident, suicide, or something altogether more sinister? And is it linked to a grisly find close to the site of the gathering? Are the worlds most powerful men at risk from a killer? While the government and secret services attempt to hush the whole thing up, Rebus knows he has only seventytwo hours to find the answers.
